Chemistry - CHEMICAL BONDING Question with Solution | TestHub
Considering VSEPR and find number of molecule(s) in which two "O" atoms are opposite to each other at central atom :-
O₃, CO₂, SO₂Cl₂, XeO₃F₂, XeO₂F₄, XeO₄
Answer:
Solution:
1. O₃: The central O atom has only one O atom attached, meaning there is no pair of O atoms opposite each other.
2. CO₂: This molecule is linear (O=C=O), with the two O atoms positioned at to each other.
3. SO₂Cl₂: This molecule is tetrahedral around the S atom. The two O atoms and two Cl atoms occupy tetrahedral positions, so the O–S–O angle is not .
4. XeO₃F₂: This molecule has a trigonal bipyramidal geometry. The more electronegative O atoms occupy equatorial positions, not opposite positions.
5. XeO₂F₄: This molecule has an octahedral geometry. The two Xe=O bonds occupy trans (opposite) positions.
6. XeO₄: This molecule is tetrahedral, so the O atoms are not opposite each other.
Therefore, the molecules having two O atoms opposite to each other are CO₂ and XeO₂F₄.
